In this type of conveyer belt, the heli-xes produce a diagonally ribbed surface which tends to cause the belt to creep laterally -'when passing around rollers or over sup- Heretofore, efforts have tendency of the belt to creep in one lateral direction, as by dividing the belt into sec- 1 tions which are placed end to .end to form the belt, the strands Qfcertain sections being in the form of left hand helixes and the strands of other sections being in the form of right hand helixes, but it will be seen that in such structures there is tendency to displacement of the belt laterally on zigzag es. 4 J Stated broadly, my invention contemplates the provision of belt sections that are divided on a line extending longitudinally of the belt, and has for one-of its ob ects the provision of a belt of the character referred to wherein the form of connectlon 1s such as to render the belt readily flexible in passing around pulleys or rolls even of rel-' atively small diameter, and wherein there is no substantial amount pf driving strain.

A form which my invention may take is shown in the accompanying drawings, wherein Figure 1 is a diagrammatic view that is representative of a conveyer' belt made of two sections divided on a line extendinglongitudinally of the belt that have right NT OFFICE 207,844.

Fig.2 is aview showing a manner in ordinarily have contact with the rollers (not shown), will extend diagonally as indicated bythe diagonal "lines of Fig. 1. By this arrangement, when the belt is driven in the direction indicated by the arrow in Fig. 1, the sections will tend to creep in the directions indicated by the arrows in Fig. 2 thereby exerting a tensional force upon the connection between the sections, so that the belt will lie. flat. If the diagonal lines converged withrespect to. the path of travel of the belt, as in case the belt were driven in the direction opposite tothat indicated by the arrow in Fig. 1, the sections would tend to move toward the longitudinal center line of the belt and exert a compressive forceat their line of juncture, thereby causing the belt to bulge at its mid portion, which The strands of adjacentbelt sections are directly connected toone another, by so bending the ends of adjacent strands of the respective belt sections that they have flexible interlocking connection with one another, as shown'at 11 and 12. The belt may bend readily in passing around a roller, an there is no great driving strain imposed upon the connecting means. The joints 11 and 12 are so formed that they will not Eroject above the upper plane of the belt.

changes maybe made therein, without departing from the spirit and scope of the lnventlon,

The term helical, as applied to the wires described herein and as t at term is used in the claims, is not-to be construed as limited to wires which are wound in true helixes but is to be construed broadly enough to cover, for example, wires which are wound as, a helix and flattened to some-jextent in the planes of the top andbottom of the belt.

I. claim as my invention:

1. A woven wire conveyer composed of 'two'longitudinal sections joined together substantially. at a longitudinal center line of the conveyer, each section being composed of apluralit of interwoven helieally wound wires exten ing transversely of the section, the wires of one section having a-right hand twist and those of the other section having a left hand twist, the said belt being assembled with. adjacent wires of the two sections in line transversely ofthe'belt, the inner ends of each pair of ad'acent wires being directly connected Itoget er independently. of the connection between other wires.

2. Conveyer belt structure comprising a plurality of pairs of helical strands, each pair of strands comprising one strand of right hand twist and one strand of left hand twist' aligned transversely of the-be1t,'*one end of each strandbein connected to an end of the aligned stran ,each pair being interwoven with the adjacent pairs of wires, and the connection between the wires of each main being independent of the connections tween other pairs of wires.

3. A conveyer belt composed of two longitudinally extending sections, each section composed of helical members extending crosswise of the section and interlocking, the

members of. one section being 'reversel ranged to those of the other section wit the members of the sections arranged in rows, and the members of one section m alignment with those of the other section, and an im-
